<h3 id="rationale">Rationale:</h3>
<p>Contrary to popular belief, there is no command or syntax
<code>./</code> that runs a file.</p>
<p><code>./myfile</code> is simply the shortest path equivalent to
<code>myfile</code> that specifies a directory and therefore causes a
shell to run it as-is, instead of trying to find its directory using
$PATH.</p>
<p>Therefore, to run a file in the current directory, use
<code>./myfile</code> and not <code>./ myfile</code>.</p>
